During the metaphase stage of mitosis spindle fibres attach to chromosomes at

Options

(a) Centromere
(b) Kinetochore
(c) Both centromere and kinetochore
(d) Centromere, kinetochore and areas adjoining centromere

Correct Answer:

Kinetochore

Explanation:

Kinetochores are small disc – shaped structures at the surface of the centromeres which serve as the sites of attachment of spindle fibres to the chromosomes that are moved into position at the centre of the cell. Hence, the metaphase is characterised by all the chromosomes coming to lie at the equator.
